card rescue software

[Godfrey DiGiorgi]

I remember some discussion here a week or two back regards salvaging  
files from a CF or SD card. I'm not at home and don't have access to  
my archives just at present ...

What was the file recovery software used? Friend of mine has a  
Sandisk Extreme III 4G card with a bunch of RAW image files on it  
that needs rescue.

thanks
Godfrey
